Application developers build and scale blockchain applications using Allium's realtime infrastructure, powering everything from high-performance wallets to realtime dashboards. ## Common Use Cases Live balances, transaction history, and activity feeds for wallet applications Up-to-date trading data, liquidity metrics, and token screeners Live portfolio tracking, performance insights, and trading history Realtime alerts and anomaly detection for security applications ## Wallets Wallet providers use [**Realtime APIs**](/api/developer/overview) and [**Datastreams**](/datastreams/overview) to power their UX and backends with realtime [**enriched transaction data**](/api/developer/wallets/overview) and [**block-level wallet balances**](/api/developer/wallets/overview). Wallets [**benefit**](https://www.allium.so/post/the-inside-story-of-the-jup-airdrop-at-phantom) from Allium's horizontally scalable infrastructure for consistent stability throughout peak network traffic (up to 1K+ RPS). | Use Case | Allium's Solution | Customer Example | | :------------------------------------------------------------------------- | :-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | :---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Realtime Wallet Activity** (Transactions, Swaps, DEX trades, NFT trades) | Allium Realtime Wallet API Activities endpoint delivers **pre-interpreted wallet event activity history** for any set of wallets and consolidates data for all relevant wallet events into one table.
